Relay 4 channel

4 Channel 5V Relay Module 10A

This small 4 Channel Relay Board works from a 5V supply for the relays and between 1V and 5V for the switching signal. It uses a transistor and opto-isolator to switch the relay on so can be connected directly to a microcontroller pin.

Switches up to 10Amps. Rated at up to 250V
